Abstract:
A system is provided and may include a compressor functioning in a refrigeration circuit. An ambient temperature sensor may produce a signal indicative of an ambient temperature. Processing circuitry may calculate an energy efficiency rating of the refrigeration circuit and may generate a relationship of the calculated energy efficiency rating and ambient temperature. The processing circuitry may compare the calculated energy efficiency rating to a base energy efficiency rating to determine if a fault condition exists.
